Meta Data

Sample Preparation: Bacterial proteins have been precipitated by trichloroacetic acid (TCA)-acetone precipitation method. The precipitated protein sample were loaded in 12% SDS-PAGE. The gel was stained with 0.5% Coomassie brilliant blue R-250, then destained until the appropriate background was obtained. The bands were alkylated with 55 mM iodoacetamide in 50mM ammonium bicarbonate at RT for 30 min.

Peptide Separation: The samples were digested with sequencing grade trypsin from bovine pancreas (Roche, Risch-Rotkreuz, Switzerland). Desalting of peptides is performed using C18 Pierce® Zip tips (Thermo Fisher Scientific, Waltham, MA, USA) before loading in a Nanospray capillary column (PepMapTM RSLC C18, Thermo Fisher Scientific, Waltham, MA, USA), and subjected to sequencing by MS/MS in Q-Exactive HF (Thermo Fisher Scientific, Waltham, MA, USA).

Protein Characterization: The spectra were analyzed using Proteome Discoverer (Version 2.2) against the NCBI protein database.
